He's standing at the bar in the Empire Arms Hotel, drunk, wearing a blue suit. You can't talk to him... he's too drunk. You need to follow him when he goes to get a cigarette by the elevators, then silently kill him and take his picture.

do i have to break the masquerade early to have this quest?

I usually break it in Santa Monica when I send the thin blood to kill the president with the Holy Stake You receive the email after your first visit Silvia so yes, the sooner you break the Masquerade the sooner you get this quest

Just make sure to break the masquerade and meet her before you get to Hollywood. If you do, she will email you the quest and it starts, and in the email she specifically states to hurry and do this now. Basically she's saying that if you ignore the quest and get to Hollywood, then the reporter had already turned the picture of the Nosferatu in to the newspaper and you will had failed the quest.
